No song repeat fraud

I have a complaint about the Smile No Repeat Song promotion!!! On Tuesday 14 June 2022 a song was played twice, first time it was played before lunch and the second time it waa played at about 3:30 the afternoon. I then called the station and was given the live show number which I called and phone was answered by a guy......I didn't ask his name.....I told him I was calling for the no repeat song and he said which song was it and before I could answer he lead me by saying Is it Whitney Houston and I completed his sentence by giving the name of the song which is How will I Know......and he wwnt on and said 15 other people called and gave the same song! He told me to email Justine and Justine is denying that the song played twice!!! How can 15 people be wrong????!!! Is this a fraudulent promotion or what??? I am sure that your calls are recorded and please go to my call with one of your employees and hear that he said I was not the only one that called and said the same song!!! This is wrong!! After a couple of emails going back and fourth with Justine she finally sends me an email to say yes there was a repeat after all and the first caller wins. I went to look at ghe completion rules and no where does it say the first caller wins. I told her that that is not mentioned on the competition page but she didn't reply. I noticed today on the radio that tbey are now saying the first caller wins which is something THEY DIDN'T SAY BEFORE!!
